In some cases, such as the popular Wind Map, the geoweb affords new ways of presenting information that seem to be unlike anything possible in traditional cartography. Are there conventions for these emerging map types? What can be learned from older maps, or from present-day non-cartographic visualizations?

On the other hand, geoweb cartographers are confronted with many of the same challenges as traditional cartographers, such as how to place a large number of city labels on a map. However, on the geoweb these tasks cannot be done by hand, because web maps frequently must function at multiple scales and with massive, dynamic data sources. Can label placement algorithms create maps as well as human cartographers, and do the same cartographic “rules” apply?

Join the discussion and let us know whether you think geoweb cartography is truly a new paradigm, or whether cartographically speaking, “there’s nothing new under the sun”.

As always, the #geowebchat takes place on Tuesday at noon PDT (3pm EDT, 8pm BST). Log on to twitter and follow the hashtag #geowebchat to listen in or join the conversation.
